This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X225-30, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ32X225-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X225-30 is a double-acting profile-type standard cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X225-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X225-30
The AirTAC SUJ32X225-30 is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 195 to 225 mm stroke. The nominal 225 mm is the maximum. This bore uses a 1/8" port, a 12 mm rod, and 21 mm adjustable cushions.
This SUJ model is discontinued; the direct replacement is the SAUJ32X225-30, retaining the same profile body, bore, stroke, force, port, and FA/LB mounting. The upgrade path moves sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. The stop screw sets end position only—it is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X225-30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X225-30 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ32X225-30 Is Used
Variable Pitch Pushing
Feeding parts of differing lengths on a line by dialing in the extend stroke from 195 to 225 mm without swapping the cylinder.
Adjustable Diverter Gate
Tuning a sorting gate's reach on-site to handle changing package widths, using the stop screw to set the exact end position.
Prototype Clamp Positioning
Dialing in a clamping datum during short-run machining, trimming the extend stroke up to 30 mm to find the optimal contact point.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X225-30 with the SAUJ32X225-30
To replace the discontinued SUJ32X225-30, specify the direct replacement SAUJ32X225-30, which matches the 32 mm bore, 225 mm max stroke, 1/8" port, and FA/LB mounting. Choose the 30 mm adjust window if your mechanism needs field tuning between 195 and 225 mm. Because this SKU lacks a magnet (-S), it cannot take a switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors if you add an -S suffix. For this 225 mm stroke, check side-load guide spacing. Remember the stop screw is not a brake—add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X225-30
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ32X225-30 FAQ
Yes, the SUJ32X225-30 is discontinued. The direct replacement is the SAUJ32X225-30, matching the 32 mm bore, 225 mm stroke, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The nominal 225 mm extend stroke can be shortened by up to 30 mm on-site (195 to 225 mm usable). The stop screw sets end position but is not a load lock.
